核心提示： “鋰電池放電放得越盡，電池的損耗就會越大，”艾克郎大學，幫助美國太空總署NASA研究延長電池壽命的電子工程教授Tom Hartley，說到，“給電池充電充得越滿，電池的損耗也會越大。鋰電池最好是處于電量的中間狀態，那樣的話電池壽命最長。”
　　淺(qian)談(tan)鋰電池放電的誤區

　　“鋰電池(chi)(chi)放電放得(de)越(yue)盡(jin)，電池(chi)(chi)的(de)(de)損(sun)耗(hao)就會(hui)越(yue)大，”艾(ai)克郎(lang)大學，幫助美國太空總署NASA研究延長電池(chi)(chi)壽命的(de)(de)電子工程教授Tom Hartley，說到，“給電池(chi)(chi)充(chong)電充(chong)得(de)越(yue)滿，電池(chi)(chi)的(de)(de)損(sun)耗(hao)也會(hui)越(yue)大。鋰電池(chi)(chi)最好是處(chu)于電量的(de)(de)中間狀態，那樣的(de)(de)話電池(chi)(chi)壽命最長。”

　　首先，過(guo)高和過(guo)低的(de)電(dian)(dian)(dian)(dian)(dian)量(liang)狀(zhuang)態(tai)對(dui)鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)壽(shou)命(ming)有最不利的(de)影響(xiang)，而充放(fang)電(dian)(dian)(dian)(dian)(dian)循環次(ci)數(shu)(shu)反而是(shi)次(ci)要 的(de)。其實，大(da)多數(shu)(shu)售賣電(dian)(dian)(dian)(dian)(dian)器或電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)上(shang)(shang)標識的(de)可(ke)反復(fu)充電(dian)(dian)(dian)(dian)(dian)次(ci)數(shu)(shu)，都是(shi)以放(fang)電(dian)(dian)(dian)(dian)(dian)百(bai)分(fen)之80為(wei)基準測(ce)試得(de)出(chu)的(de)。實驗表明(ming)，對(dui)于(yu)一些(xie)筆記本電(dian)(dian)(dian)(dian)(dian)腦的(de)鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，經常讓電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓 超過(guo)標準電(dian)(dian)(dian)(dian)(dian)壓0.1伏(fu)特，即(ji)從4.1伏(fu)上(shang)(shang)升到4.2伏(fu)，那(nei)么電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)壽(shou)命(ming)會減半，再提高0.1伏(fu)，則(ze)壽(shou)命(ming)減為(wei)原來(lai)的(de)3分(fen)之一;長期(qi)低電(dian)(dian)(dian)(dian)(dian)量(liang)或者無電(dian)(dian)(dian)(dian)(dian)量(liang)的(de)狀(zhuang)態(tai)則(ze) 會使電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)內(nei)部(bu)對(dui)電(dian)(dian)(dian)(dian)(dian)子移動的(de)阻力越來(lai)越大(da)，于(yu)是(shi)導致電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)容量(liang)變小。美(mei)國宇航(hang)局NASA讓其哈勃太(tai)空望遠鏡(jing)上(shang)(shang)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)消耗(hao)電(dian)(dian)(dian)(dian)(dian)量(liang)設(she)定在總容量(liang)的(de)百(bai)分(fen)之10，以確(que)保 電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)可(ke)以反復(fu)充放(fang)電(dian)(dian)(dian)(dian)(dian)10萬次(ci)而不必更新。

　　其次，溫度對鋰(li)電(dian)池(chi)(chi)壽命也(ye)有較大的(de)(de)影響(手機和其他小型(xing)電(dian)子設備(bei)對此(ci)點可(ke)忽略)。冰(bing)點以下(xia)的(de)(de)環境有可(ke)能使鋰(li)電(dian)池(chi)(chi)在(zai)電(dian)子產(chan)品打開的(de)(de)瞬間(jian)燒毀，而過熱的(de)(de) 環境則會縮減電(dian)池(chi)(chi)的(de)(de)容量。因此(ci)，如果(guo)筆(bi)電(dian)長(chang)(chang)期使用外接(jie)電(dian)源也(ye)不將電(dian)池(chi)(chi)取下(xia)來，電(dian)池(chi)(chi)就(jiu)長(chang)(chang)期處于(yu)筆(bi)記本排(pai)出的(de)(de)高熱當(dang)中，更主要(yao)的(de)(de)是，電(dian)池(chi)(chi)長(chang)(chang)期處于(yu)百分(fen)之100 的(de)(de)電(dian)量狀態，很快(kuai)就(jiu)會報廢。

　　由以(yi)上(shang)，我們可以(yi)總結出以(yi)下幾點確保(bao)鋰(li)電池(chi)容量和(he)壽(shou)命的注意事(shi)項：

　　目前大多數電(dian)(dian)子產品的(de)(de)電(dian)(dian)池(chi)(chi)都采用(yong)鋰(li)電(dian)(dian)池(chi)(chi)，鋰(li)離子電(dian)(dian)池(chi)(chi)自1990年問(wen)世以(yi)來，因(yin)其卓越的(de)(de)性能得到了迅猛(meng)的(de)(de)發展(zhan)，并廣泛地應用(yong)于社(she)會，鋰(li)電(dian)(dian)池(chi)(chi)生(sheng)產商也(ye)因(yin)此得到了最(zui)大規模的(de)(de)發展(zhan)。不需要(yao)將鋰(li)電(dian)(dian)池(chi)(chi)充到百分之100滿電(dian)(dian)，更不要(yao)將電(dian)(dian)量使用(yong)殆(dai)盡(jin)。在(zai)情況允許的(de)(de)情況下，盡(jin)量使電(dian)(dian)池(chi)(chi)的(de)(de)電(dian)(dian)量維(wei)持在(zai)半滿狀態附近，充電(dian)(dian)與放電(dian)(dian)的(de)(de)幅度越小越好;

　　通(tong)用(yong)Chevy Volt電(dian)動車的出廠設(she)計就(jiu)是(shi)強制將電(dian)池(chi)電(dian)量維持在(zai)20%至80%，而蘋果筆(bi)電(dian)的內(nei)置(zhi)電(dian)池(chi)可能也是(shi)運(yun)用(yong)了這(zhe)一方法(包(bao)括其(qi)他一些(xie)筆(bi)電(dian)和電(dian)子產(chan)品)，讓電(dian)池(chi)的可充放電(dian)周期數增加。

　　不要將鋰電池(尤其是筆記本鋰電池)長期在設備使用外接電源、充電器的情(qing)況下工作。就算您的筆記本散熱良好(hao)，長期(qi)百分之100的電量就等于對鋰電池的謀殺。

　　1. 如果(guo)你長期用外接電(dian)源(yuan)(yuan)為筆記(ji)本(ben)電(dian)腦(nao)供電(dian)，或者電(dian)池電(dian)量已經超過(guo)80%，馬上(shang)取下(xia)你筆記(ji)本(ben)的電(dian)池、平時充(chong)電(dian)不需將(jiang)電(dian)池充(chong)滿，充(chong)至80%左(zuo)右即(ji)可;調(diao)整操(cao)作(zuo)系統的電(dian)源(yuan)(yuan)選項，將(jiang)電(dian)量警報調(diao)至20%以(yi)上(shang)，平時電(dian)池電(dian)量最低(di)不要低(di)于20%，在下(xia)降到(dao)20%以(yi)前(qian)即(ji)要進行充(chong)電(dian);

　　2. 手機等小(xiao)型(xing)電(dian)子設備(bei)，充(chong)好(hao)電(dian)了就應立刻斷開(kai)電(dian)源線(包(bao)括(kuo)充(chong)電(dian)功能的USB接(jie)口)，一直接(jie)著會損害電(dian)池;要經常(chang)充(chong)電(dian)，記起來就充(chong)，但(dan)不(bu)必非得把電(dian)池充(chong)滿;

　　3. 無論是對筆記(ji)本(ben)還是手機等，都一定不要讓電池耗盡;

　　4. 如果要外出旅行，用電池充電器充滿吧(ba)，但請記(ji)得(de)在條件(jian)允許的(de)情(qing)況(kuang)下(xia)隨時為電器充電，為了(le)電池(chi)壽命(ming)，一定不要等到(dao)電池(chi)放干。
